Other Activities

1. I studied in the field of revegetation works and erosion control engineering at Forestry and Forestry Products Research Institute, Ministry of Agriculture, Forestry and Fisheries from 1991 to 1992;
2. I have been engaged in teaching and researching in the forestry and soil and water conservation, and participated in a large amount of technology consult and training concerning on afforestation and watershed harnessing for various engineering projects in China. Lectured students in Silviculture, ecological forestry, revegetation engineering for erosion control, agriforestry and so on for many years.
